ast.params.map is not a function error

Moved from https://github.com/ember-template-lint/ember-template-lint/issues/2027 - I was seeing an error when attempting to fix the no-model-argument-in-route-templates.

Should this statement be guarded in a ast.params.length check? https://github.com/ember-template-lint/ember-template-recast/blob/v5.0.3/src/parse-result.ts#L346

The ast used on line 346 can be of one of the following types: https://github.com/ember-template-lint/ember-template-recast/blob/ec7c070c73db48a122dcf6608e5653de10226fa4/src/parse-result.ts#L274-L278

Each of these types of node have a params property. It means that ast.params is never supposed to be something else than an array.

Have you been able to isolate the template causing the ast.params.map is not a function error error? If yes do you mind sharing it?
